1 answer:

4 0

The equation which can determine v, the number of visits Ariana must make to earn a free movie ticket is given by :76=25+8.5v

v=6

What is the total number of points required for a free movie ticket?

The total number of points that Ariana needs to watch a free movie is 76 points, which can be earned by the sum of signing up points plus the number of visits(v) multiplied by the points per visit, 8.5 points

76=25+8.5v

We can make v the subject of the formula

76=25+8.5v

76-25=8.5v

51=8.5v

v=51/8.5

v=6

A study is done to find the 95% confidence interval for the difference in means between the ACT scores between two schools in a

Kitty [74]

Solution :

95% confidence interval for the difference between the means of ACT scores between two schools, is given by :

$[(\overline X_1 - \overline X_2)-ME, (\overline X_1 - \overline X_2)+ME]$

$\overline X_1 = 25.90 , \ \ \ \overline X_2 = 27.70$

$S_1=3.49, \ \ \ S_2 = 2.47$

$n_1=39, \ \ n_2=37$

M.E. , Margin of error,

$=t_{n_1+n_2-2,0.025} \times \left( s \sqrt{\frac{1}{n_1}+\frac{1}{n_2}}$

$s^2 = \frac{(n_1-1)S_1^2+(n_2-1)S^2_2}{n_1+n_2-2}$

$=\frac{38(3.49)^2+36(2.47)^2}{39+37-2}$

= 9.222

s = 3.03

$t_{74,0.05} = 1.99$

$M.E. = 1.99 \times 3.03 \times \sqrt{\frac{1}{39}+\frac{1}{37}}$

= 1.4

Therefore, 95% CI = [(25.90-27.70) - 1.4 , (25.90-27.70) + 1.4]

= [-3.2, -0.4]

Therefore, the lower bound is -3.2
